Anritsu adds dual wavelength measurement capability to O/E calibration modules

November 18, 2015

Anritsu Co. introduces two options for its MN4765B series of O/E calibration modules that help to create a highly accurate, flexible and cost-effective solution for the characterization of optoelectronic devices such as modulators, photoreceivers and integrated optical transceiver modules. With these new options, the MN4765B can be used with the MS4640B VectorStar® Vector Network Analyzer (VNA) family to perform optoelectronic measurements up to 70 GHz at both 1310 nm and 1550 nm wavelengths.

Option 71 allows the MS4765B to be used with the VectorStar VNA to conduct optoelectronic measurements from 70 kHz to 70 GHz in the 1310 nm range, while Option 72 provides measurements from 70 kHz to 70 GHz at both 1310 nm and 1550 nm to be made. Both options use a NIST-characterized photodiode as the primary standard, for greater E/O and O/E measurement accuracy when compared to alternative methods.

The MN4765B module, combined with the MS4640B VNA, provides a simplified approach for optoelectronic measurements and is an economical alternative to conventional total-system approaches currently used. The MN4765B optical modules are designed with an InGaAs photodiode that converts modulated optical signals to electrical signals. The photodiode has exceptional bandwidth response to 70 GHz. Additional circuitry for temperature and bias stability are also incorporated into the modules.

With the new wavelength options, the MN4765B O/E calibration module can be used to conduct dual wavelength optoelectronic measurements to characterize components during R&D and manufacturing. It is also well suited for universities and research labs where modulation rates up to 70 GHz at dual wavelengths are being explored.

VectorStar VNAs provide more accurate measurements over single-sweep frequency ranges of 70 kHz to 20 GHz, 40 GHz, 50 GHz, 70 GHz, 110 GHz, 145 GHz and a variety of discrete bands to 1.1 THz. Unlike other VNA solutions on the market, the VectorStar family is built on a stable, modern platform that can be easily upgraded across a range of functionality and performance. The MS4640B VNA series offers a high level of performance, so device modeling engineers can accurately and reliably characterize their devices. R&D engineers can achieve the last fraction of a dB out of their state-of-the-art designs and manufacturing engineers can maximize throughput without sacrificing accuracy.
